Title: Method for inspecting underwater welding
Inventor: UEDA KOHEI
IPC: B23K9/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To confirm an underwater welding state easily with eyes by applying a hydraulic pressure equal to the water depth to one side of an underwater object and applying the atmospheric pressure to a predetermined region including a welding line on the other side. SOLUTION: In the case of a pipe, water is injected into the pipe and a part thereof is opened thus applying a hydraulic pressure equal to the water depth. On the other hand, the atmospheric pressure is applied to a predetermined region including a welding line on the other side. An inspection container 1 is thereby fixed while closing all valves and then pressurized gas is supplied from an atmospheric pressure valve 5 by opening a lower drainage valve 4. Consequently, water in the container 1 is drained through the drainage valve 4 and the gas is stored in the upper part of the container 1. Subsequently, an atmospheric pressure valve 6 is opened to supply the atmospheric pressure into the container 1 through a pressure resistant tube 7. Consequently, hydraulic pressure acts on the inside of a welding line and the atmospheric pressure prevails on the other side.  Since water leaks through an incompletely welded part due to the pressure difference, incomplete welding can be checked.

Abstract: PROBLEM TO BE SOLVED: To make power consumption low with simple constitution by preventing line-of-sight detecting operation from being performed by a line-of- sight detection means when a discrimination means discriminates that an eyeball does not exist even when a signal is outputted from a signal output means. SOLUTION: When a detecting light irradiation part 1 irradiates the eyeball with light, reflected light from the eyeball of the irradiating light is received and photoelectrically converted by a photoelectric conversion part 2. The line-of- sight direction of a photographer is detected in a line-of-sight direction arithmetic operation part 3 based on a signal from the conversion part 2. Meanwhile, when an ocular state detection part 4 detects whether or not the photographer looks in a finder, a detection mode is switched to a line-of-sight detection mode or a low consumption detection mode in accordance with the ocular state by the detection part 4. A control part 6 controls the operation of the irradiation part 1 and the arithmetic operation part 3 based on the signal from a mode switching part 5.  In the case of discriminating that the eyeball does not exist even when the signal is outputted from the irradiation part 1, the line-of-sight detecting operation is not performed.

Abstract: PURPOSE:To enable the liquid level of a medium to be kept at more than a prescribed value even in case of emergency when a circulating pump for the medium breaks down by placing a medium storage drum above a liquid level of the medium in a medium evaporator at the time of normal operation. CONSTITUTION:A medium storage drum 8 is placed above the liquid level of a medium in a medium evaporator 4 at the time of normal operation. When a medium circulating pump 2 gets out of order, or the liquid level of the medium in the medium evaporator 4 decreases abnormally, a pressure difference between the medium evaporator 4 and the medium storage drum 8 arises, and consequently, the medium is supplied from the medium storage drum 8 to the medium evaporator 4 so that the liquid level of the medium in the medium evaporator 4 can be kept at more than a prescribed value. And therefore, the area, in which the medium in the evaporator 4 comes in contact with a heat-transfer pipe 28, can be made to more than a prescribed value. Thereby, the medium can always be evaporated by a prescribed quantity, and therefore, the pressure and temperature of the medium in the medium evaporator 4 can be prevented from decreasing abnormally.
